A thin layer of tissue surrounding an organ, lining a cavity or separating adjacent structures or cavities.

in cells, the "plasma" or "cell" membrane is a sheetlike structure that surrounds cells, contains their inner contents, and regulates the movement of materials in and out of the cell. At the tissue level, membranes (tissues usually composed of cells) also serve to surround and regulate material transport, but do so at a larger level.

A thin pliable covering or lining. The plasma membrane that surrounds an animal cells consists of a double layer of fat (lipid) molecules, which protects the cell contents from the external environment.

The virus sheds this membrane when it enters a new host cell, and collects a new membrane as it leaves the host to infect other cells.
